How do you deal with a booty call who suddenly decides she can't fool around with you anymore because she wants to find a nice guy and settle down?

A girl you picked up in a club years back and got to know because she's a club promoter who you've been casually shagging for the last few years who's recently hit 30, suddenly has a big outburst at you, about how she needs to "stop having flings and think about (her) future". She then threatens to withdraw or make booty calls more infrequent and up to when she says so not when you want her.

And how she'd been wanting to say it for a while, after you've made it repeatedly clear to her you're not interested in a relationship, that your career comes before settling down with someone, you want to travel, live abroad, you're not even sure you want to have kids, etc.

I figured it was a sh*t test and went with SiNfUl's tip of rolling with it, and being like "Yeah baby I'm totally not the guy for you. Go find a nice guy at online dating site." Then being like "It's just about pleasuring you baby blah blah blah".

What would you do?

Good chance the milestone birthday reminded her of her ticking baby clock. It may pass or it may not. Keep playing it cool in the meantime. She may actually want to settle down, in which case you'll have to recruit a replacement. But don't forget, once she starts desperately looking for a husband, she'll frequently become frustrated. At that point you should let her take off some pressure with your whistle...
